Abstract

The provided is a single side wheel anti-lock braking method and system based on a dual-microcontroller unit (MCU) electronic parking brake (EPB) system. The method includes the following steps: S1: calculating a real-time single side slip ratio, including a real-time left side slip ratio and a real-time right side slip ratio; S2: comparing the real-time single side slip ratio with a preset locking slip ratio, and adjusting a clamping force and a clamping time step of a rear wheel; S3: comparing a number of single side release commands within a set time with a threshold, and determining a road condition; and S4: executing a braking strategy based on the road condition. With the single side wheel anti-lock braking method and system based on a dual-MCU EPB system, the provided can perform anti-lock control on single side wheels based on real-time wheel speed information and identify road conditions.
